The turned-over edges 26 and the flange 27 are cut away adjacent the bot- .tom of the plate 25 to permit-the chainl 20 to pass therethrough. .As theA skylight is raised, the jack screw '15 will be swung lslightly from its'vertical position, vand befcause ofthe pivoted relation betweenA the collar 12. A spindle 17 is formed integral with, orotherwise secured to, the collar, 12,

' duces rotation of the pinion 16 :and thereby produces upward or downward movement of u i port, a collar pivoted to said support, `a jack 105 1 the vjack screw 15.v f u A suitable sprocket 19 maybe formed integral with the beveled gear 18, or be otherwise secured thereto, and a iieXible element,

such as a sprocket chain 20, is vadapted to pass thereover, so that'a downward pull of either of the depending strands or `lengths of vchain will cause rotation of the beveled -gear 18.

The lowerl end of the jack screw 15 is` provand a beveled gear 18 is rotatably mountedv collar 12 and the support 10, the jack screw 15 Vmay assume any `'position necessary. Becauseof this swinging movement, it is essential that the upper end of the jack screw 15 have a limited pivotal relation with ref spect to the skylight S.' i It will be understood that various changes in thedetails of construction may be madek without departing from the spirit orV scope` of the invention as dened bythe appended claims. y w

Iclaim:- f y 1.- A skylight adjuster lcomprising aj'supscrew slidable withiny said collar, abeveled pinion threaded on to said jack screwand normally restingy upon said collar, fa beveled gear rotatably mounted upon v.said collar and meshing with said pinion, a flange carried'by said beveled .gear and passing over said pinion, asprocket securedto said. beveled gear, a chain engaging lsaid sprocket `i adapted to produce rotation thereof, means for preventing disengagement of said chain from said sprocket, and means for pivotally securing said jack screw to a skylight.

2. A skylight adjuster comprising a bracket, a pair of spaced lugs provided upon said bracket, a collar having a projection' disposed between said lugs, a bolt passing through said lugs and projection` so as to pivot said collar to said bracket, a jack screw slidable within said collar, a beveled pinion threaded onto said jack screw, a spindle upon the collar, a beveled gear rotatable upon the spindle and meshing with said pinion, and means for rotating said beveled gear.

3. A skylight adjuster comprising a bracket, a pair of spaced lugs provided upon said bracket, a collar having a projection disposed between said lugs, a bolt passing through said lugs and projection so as to pivot said collar to said bracket, a jack screw slidable within said collar, a beveled pinion threadedy onto said jack screw, a spindle upon the collar, a beveled ygear rotatable upon the spindle and meshing with said pinion, and means including a sprocket and a chain for rotating said beveled gear, and means for preventing` disengagement between the sprocket and chain.

4. A skylight adjuster comprising a bracket, a pair of spaced lugs provided upon said bracket, a collar having a projection disposed between said lugs, a bolt passing through said lugs and projection so as to pivot said collar to said bracket, a jack screw slidable within said collar, a beveled pinion threaded onto said jack screw, a spindle upon the collar, a beveled gear rotatable upon the spindle and meshing with said pinion, means including a sprocket and a chain for rotating saidv beveled gear, and means for maintaining said beveled pinion adjacent said collar.

In testimony whereof I have signed my name to this specification.
